A novel concept, called nonadditive set-valued measure, is first defined as a monotone and continuous set function. Then the interconnections between nonadditiv
Lp(Rm × Rn) boundedness is considered for the multiple Marcinkiewicz integral. Some sizeconditions implying the Lp(Rm × Rn) boundedness of the multiple Marcin
Acrylate-modified polyurethane resin was first synthesized, and interpenetrated with unsaturated polyester resin to form IPNs and gradient IPNs which cured at r
SiC-C films with different content of SiC were deposited with r. f. magnetron sputtering followed by argon ion bombardment. These films were then permeated by h
